Gregg Phillips’ Twitter profile describes him as, among other things, the founder of VoteStand, “America’s first online election fraud reporting app. VoteStand purportedly “uses your geo-location and the user-filed report in order to provide enough evidence to pursue legal action against the person/persons committing the fraud.” Phillips has not said whether the data was extrapolated from VoteStand reports or even what his methodology is in general, turning down requests from journalist because he feared that they would “spin” his data:

As for what else Phillips could potentially be talking about, the Miami Heraldsuggests that similar claims from other sources in the past have come from a misinterpretation of a 2014 Harvard survey. Snopes, on the other hand, thinks it could tie into a conspiracy theory involving voters who registered when they signed up for health insurance under the Affordable Care Act.

However, neither theory explains Phillips’ claim that he has access to “a database of 180 million voter registrations.” Data from his own VoteStand app would not fit the bill, either. Just like when Trump claimed a man who rushed the stage at a campaign event in March had ties to ISIS, it appears that President Elect Trump just believed what he read on the internet.
